WILLIAM J.l BERGENS, OF CHICAGO, IIILNOIS, ASSIGNOR 'TO THE NOVELTY PATENTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

EXTENSION CURTAIN ROD.

Application filed October 12, 1921. Serial No. 507,237.

T 0 all whom it may concern.'

Be it known that I, IILLTAM J. BERGEN-s, a citizen of the United States of America, and a resident of Chicago, countyi of Cook, State of Illinois, have invented certain Improvements in Extension Curtain Rods, of which the following is a specification.

This invention relates to that type of eX- tension curtain rods in which a pair of telescoping sections are drawn together by a spring, the tension of which is adapted to hold the sections in supporting engagement with fixed supports on a Window frame or the like, and this improvement has for its object:

To provide a structural formation and association of parts adapted to provide a rigid and substantial support for the curtain With a minimum thickness of the parts and With which an effective and pleasing draping of the curtain is attained, all as Will hereinafter more fully appear.

In the accompany drawing:-

Fig. 1 is a rear elevation of a curtain rod embodying the preferred form of the invention.

Fig. 2, is a transverse section on line 2-2- Fig.

Fig. 3, is a detail perspective view of one of the integrally formed attaching hooks by Which the ends of the operating spring is connected to the telescoping sections of the article.

Like reference numerals indicate like parts in the different views.

Referring to the drawing, l designates the outer tubular section, and 2 designates the companion inner tubular section of the curtain rod formed to slide or telescope together, one Within the other. In the present improvement the sections l, 2, are of a shell form, preferablyv of an approximately rectangular shape in cross section, and having in their rear faces or sides centrally arranged longitudinal gaps 3 for the passage and reception of the operating spring now to be described.

4 designates the operating spring of the usual coiled type, arranged in the interior of the aforesaid rods, sections and in the gaps 3 thereof, with the outer side of the spring on a line with, or slightly inside, the rear face of the outer section l as shown, and so that no interference of the gaps along their entire length,

spring With the proper and effective draping` of the curtain Will occur.

The spring 4i is provided with attachingeyes 5 at its respective ends for engagement With hooks 6 and 7 on the respective outer and inner sections l and 2 aforesaid, and in the preferred construction the hooks 6 and 7 are formed integrally with the front Webs of the sections l, 2, by slitting the same to provide tongues which are then bent to a hook shape as illustrated in Fig. 3.

8 and 9 designate hooks or other usual attaching means on the outer ends of the respective sections l and 2 for attachment to a Window frame in the usual manner.

Having thus fully described my invention, what I claim as ne7 and desire to secure by Letters Patent is l. In a curtain rod, the combination of a pair of tubular telescoping sections having attaching means at their remote ends, and a coiled spring arranged longitudinally in the interior of said sections and attached at one end to one section and at the other end to the other section, the said sections having gaps along their entire length, said spring being introduced through said gaps into place in said sections, with the spring` attaching means accessible through said gaps.

2. In a curtain rod, the combination of a pair of tubular telescoping sections of an approximately rectangular shape in cross section and provided With attaching means at their remote ends, and a coiled spring arranged longitudinally in the interior of said sections and attached at one end to one section and at the other end to the other section, the said sections having gaps along` their entire length, said spring being introduced through said gaps into plate in said sections with they spring attaching means accessible through said gaps.

In a curtain rod, the combination of' :i pair of tubular telescoping sections having attaching means at their remote ends, and a coiled spring arranged longitudinally in the interior of said sections and attached at one end to one section and at the other end to the other section, said attaching means comprising integrally formed hooks on the respective sections, the said section having said spring being introduced through said gaps into CFI place in said sections, with the spring attaching means accessible through said gaps.

,4. a curtain rod, thecoinbination' of a pair of tubular teleseoping sections' of 'an approximately rectangular shape in cross section and provided with attaching means at their remote ends, and a coiled sp1-.ing arranged longitudinally in the interior of Said Sections and attached at one 'end to one section and at theother end to the other v of October,

section, said attaching means comprising integrallyy formed lhooks on vthe respective se@ tions, the sa'idv `sections having gaps along their entire length, said springs'hing introduced through said gaps into place in said sections, with thev spring atta-ching means accessible through said gaps.
